WebSep 1, 2012 · The intensification is preceded by the formation of a descending reflectivity core (DRC), similar to others that have been documented in some supercells recently. The DRC is associated with a rapid increase in the vertical vorticity and circulation of the low-level mesocyclone. http://grlevelx.com/gr2analyst_3/volume_renderer.htm five little bunniesWebThis is a classic volume signature for a strong tornado. A large overhang of 50+ dbz develops, a "finger" or descending reflectivity core (DRC) comes out of it, a debris blob appears at the ground level, the DRC connects to the debris blob to form a complete tube.
